According to Erie County Department of Health protocol, if E. coli bacteria counts are between 235 and 999 per 100 milliliters of water, a swimming advisory is posted for a beach. The precautionary swimming advisory will be lifted when there is no longer an environmental and public health concern, officials said.

Beaches under a precautionary swimming advisory are still open to the public for swimming, sunbathing and other recreational opportunities. However, beach users are advised to avoid swallowing lake water, wash their hands before handling food and avoid swimming with an open cut or wound or if experiencing an illness.
